Ever wanted to play Pong on a 400-foot-tall screen? Starting April 19 you can.

The arcade classic is coming to the north wall of the glass-sheathed Cira Centre. The building's lattice of LED lights will display a lo-fi ball bouncing between opposing paddles. 

Lucky gamers (there will be an online drawing) will face off from the steps of the Philadelphia Art Museum, controllers in hand.

"This is something I've been envisioning for quite a while," said Frank Lee, co-founder of Drexel's Game Design Program and the man behind giant Pong. "One of the main goals of this event is to inspire wonder and creativity in anyone who sees it, especially kids."

The splashy interactive art installation is designed to kick off the third annual Philly Tech Week in style. The weeklong bonanza of all things tech and innovation is being organized by the newly-redesigned Technically Philly.

Site co-founders Chris Wink and Brian James Kirk previewed Tech Week at an event Wednesday night. We'll have more on that later.

For now, practice up. I bet your Pong game is rusty.
